WILLIAM MCG. TOWERS AND ARTHUR R. SULLlVAN, OF ROME, GEORGIA.

PLOW.

SPECIFICATION forming part of Letters Patent No. 247,970, dated October 4, 1881.

Application filed February 19, 1881. (No model.)

To all whom it may concern:

- Be it known that we, W. M. TowERs and A. R. SULL1VAN,citizens of the United States, residing at Rome, in the county of Floyd and State of Georgia, have invented certain new and useful Improvements in Plows; and we do hereby declare the following to be a full, clear, and exact description of 'the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawin gs, and to letters or figures of reference marked th ereon, which form a part of this specification.

Our invention is designed more especially as an improvement on that class of shovelplows shown and described in Letters Patent granted to E. Barber, dated April 9, 1878, No. 202,090; and the objects of our improvements are to simplify the construction of this class of plows by substitnting` a clamping nut-bolt in lieul of rivets and dispensing with the wedges or locking-blocks.

Our invention the rel'ore consists in the novel construction and combination of parts,as will be hereinafter more fully set forth and specifically claimed. i

Figure 1 is a perspective view of our improved shovel-plow. Fig. 2 is a perspective view of the plow-standard and the bracing-bar attached to a portion of the beam. Fig. 3 is a sectionalview taken through the line x of Fig. 3, showing a front View of the standard attached to the plow-beam. i

Inthe annexed drawings, forming a part of this specification, the letter A represents the plow-beam, with the handles B and a clevis,'0, of the ordinary construction.

The letter D represents the plow-standard, to which the shovel-plow or other attachment is fastened. This standard is made of a prepared metal blank of a given length, width, and thickness, bent at its middle portion over a'former, so as to correspond with the thickness of and encircle the plow-beam intended for, and the ends are united at the bottom by introducing a block of metal and welding the parts together. The standard thus formed is now shaped, by proper means, to give the proper' pitch to the plow-shovel. The upper portion of the standard, which encircles the beam, is expanded so as to embrace and fit snugly the top and sides of the beam, as seen in the draw'ings, and that portion of the standard below the clamping-bolt runs parallel and receives the forward end of the brace and the fastening bolt or bolts of the plow attachment. The standard is attached to the plow-beam by passing it over the forward end of the beam until it reaches its seat or place of rest, where it is secured in a rigid position by means of the clamping-bolt c, passing through the perforations in the standard, which are located at a point imrnediately under the lower surface of the beam and above the Shoulders in4 the standard. This clamping-bolt in securing the standard to its seat affords a bearing for the beam, and at the same time obviates the det'ects which exist when the bolt is placed below the shoulder of the standard.

The letter E represents a diagonal brace piroted between the Vertical parallel walls of the standard at b, and the upper end of the brace is formed with an angular perforated extension,d, through which a bolt, e, passes to connect this end of the brace with the plow-beam, as seen in'l Figs. 1 and 2 of the drawings.

This improvement does away'wit-h the employment of wedges or lockin g devices for securing the standard to the plow-beam'; also, by this construction of a plow we simplify the manufacture, secure a firm connection of the slotted plow-standard, and avoid the slipping tendency of the standard upon the beam, and

consequent weakness of the parts.

It will be'observed that the pitch ofthe plowshare may be regulated, altered, and lset 'by releasing the clamping screW-bolt c, thereby permitting a movement of the 'plow standard and brace on the pivot, and then by moving the standard forward or backward on the plow-beam until the desired pitch of the share is obtained, when clamping-bolt is screwed tight in place, thereby rigidly setting the stump of the standard on the plow-beam.

What we claim as our invention, and desire to secure by Letters Patent, is- V The combination, in a plow, with the bent and shnped metal standard D, surrunding the In testimony whereof we affix our signatures p10w-hea1n,of theclampingnut-boltc,arranged in pl'esence of two witnesses.

at a point; immediately below and under the plow-beam, whereby the standard is seeurely elamped and held to the bcamwithoutthe aid Titnessesz of a wedge 01' looking-block, substantinlly as shown and described.
